# Status of OpenGL extensions in Mesa

Here's how to read this file:

all DONE: <driver>, ...
    All the extensions are done for the given list of drivers.

DONE
    The extension is done for Mesa and no implementation is necessary on the
    driver-side.

DONE ()
    The extension is done for Mesa and all the drivers in the "all DONE" list.

DONE (<driver>, ...)
    The extension is done for Mesa, all the drivers in the "all DONE" list, and
    all the drivers in the brackets.

in progress
    The extension is started but not finished yet.

not started
    The extension isn't started yet.

# OpenGL Core and Compatibility context support

Some drivers do not support the Compatibility profile or the
ARB_compatibility extensions.  If an application does not request a
specific version without the forward-compatiblity flag, such drivers
will be limited to OpenGL 3.0.  If an application requests OpenGL 3.1,
it will get a context that may or may not have the ARB_compatibility
extension enabled.  Some of the later GL features are exposed in the 3.0
context as extensions.
